NEWS RELEASE September 26, 2024
SXG Extends High-Grade Mineralisation 100 Metres Down-Dip at Apollo
Confirms VRIFY’s AI-Powered Exploration Targets
Includes 21.9 m @ 4.0 g/t AuEq and 7.8 m @ 7.5 g/t AuEq
Vancouver, Canada — Mawson Gold Limited (“Mawson” or the “Company”) (TSX V:MAW)
(Frankfurt:MXR) (PINKSHEETS: MWSNF) announces Southern Cross Gold Ltd. (“Southern Cross Gold” or
“SXG”) has released results from three diamond drill holes (SDDSC124, SDDSC127 and SDDSC128 – Figures
1 and 2) from the Apollo prospect at the 100% -owned Sunday Creek Gold -Antimony Project in Victoria ,
Australia (Figure 5).
All holes successfully intersected mineralisation in targets generated through VRIFY’s (“Artificial Intelligence”)
AI-assisted mineral discovery platform (“VRIFY AI”). Apollo East, a target identified by both the SXG
exploration team and VRIFY AI, is a new zone of potential high-grade mineralisation located approximately
200 m east of the main Apollo drill area. With these new holes, the zone has become a priority for SXG due
to AI generated targets that show the possible extension of this zone approximately 400 m to the east (Figure
3).
Highlights:
• SDDSC128 drilled a large gap and confirmed eleven vein sets from Apollo East to Apollo Deeps. The
hole extended two high-grade vein zones 20 m to 60 m down-dip and included 11 intercepts of Au >
20 g/t (up to 167 g/t Au) and 11 intercepts of Sb > 5% (up to 16.4% Sb). Selected highlights
include:
o 21.9 m @ 4.0 g/t AuEq (2.6 g/t Au, 0.8% Sb) from 505.4 m, including:
2.5 m @ 15.5 g/t AuEq (9.6 g/t Au, 3.1% Sb) from 512.4 m
o 7.8 m @ 7.5 g/t AuEq (6.8 g/t Au, 0.4% Sb) from 547.7 m, including:
0.6 m @ 81.9 g/t AuEq (74.7 g/t Au, 3.8% Sb) from 547.7 m
• SDDSC124 is the deepest hole drilled east-west at Apollo. The hole intercepted eight vein sets
across Apollo East and Apollo Deeps, extending vein domains 95 m to 105 m down -dip. Selected
highlights include:
o 6.3 m @ 6.6 g/t AuEq (2.9 g/t Au, 2.0% Sb) from 427.3 m, including:
0.5 m @ 62.2 g/t AuEq (18.2 g/t Au, 23.4% Sb) from 427.5 m
o 0.7 m @ 19.3 g/t AuEq (19.3 g/t Au, 0.0% Sb) from 795.8 m, including:
0.2 m @ 54.4 g/t AuEq (54.4 g/t Au, 0.0% Sb) from 796.3 m
• SDDSC127 drilled four vein sets (with two new vein sets identified) at Apollo East. Selected highlights
include:
o 3.5 m @ 6.2 g/t AuEq (4.0 g/t Au, 1.2% Sb) from 423.2 m, including:
1.0 m @ 19.4 g/t AuEq (11.7 g/t Au, 4.1% Sb) from 425.8 m
• Eighteen holes are currently being processed and analysed with an additional five holes in progress.
• Mawson owns 96,590,910 shares of SXG (48.7%), valuing its stake at A$299.4 million (C$275.4 million)
based on SXG’s closing price on September 25, 2024 AEST.
Michael Hudson, Mawson Interim CEO and Executive Chairman, states: "We are back at Apollo with
these three drill holes, that continue to show Apollo is improving with further drilling, especially at depth.
“Each hole delivers a unique outcome: SDDSC128 demonstrates continuity of high-grade zones with 20
m to 60 m extensions, while SDDSC124 expands mineralisation 100 m down dip in the deepest hole drilled
east-west at Apollo. Not to be outdone, SDDSC127 drilled four vein sets (with two new vein sets
identified ) at Apollo East.
“The common thread linking all drill holes at Apollo East is the confirmation of the geological target by VRIFY
AI. Using an unbiased approach to mineral exploration, VRIFY AI identified mineralisation patterns within
multiple layers of data from Sunday Creek to successfully delineate the potential for additional mineralisation
at the Apollo East target. Working alongside the SXG exploration team, Apollo East has demonstrated the
effectiveness of VRIFY AI in confirming new targets at Sunday Creek while enha ncing the precision and
execution of geological targeting by the team.
“Intersecting high grade mineralisation in our initial AI generated targets gets us very excited about testing
the other AI targets that we have identified, both at Apollo East and beyond. It’s fascinating to plug these
early results into VRIFY’s AI model and watch the targets evolve in real-time, further refining where we look
next across our 12 km of mineralised strike extensions (Figure 4). No doubt we’re witnessing a step-change
in how mineral exploration is conducted, where AI- assisted mineral discover y platforms like VRIFY will
become a standard additional tool for all geological teams.
“These exciting gold-antimony drill results that demonstrate high-grades and continued growth of the project,
the Company has already drilled and is planning a significant number of further holes under and to the east
of Apollo.”
Drill Hole Discussion
The successful drill results announced today demonstrate how AI generated targets can complement SXG’s
geological targeting program at Sunday Creek through an innovative approach to mineral exploration.
Additional drilling at Apollo East and at the Christina Target, both of which have been identified as high-
priority targets by VRIFY AI and the Company’s technical team, is either currently underway or expected to
commence in the near term (Figure 3).
SDDSC124 is the deepest east to west drill hole (parallel to the ladder “rails”) drilled at the Apollo prospect.
The hole intercepted eight high -grade vein sets across Apollo East and Apollo Deeps (Figures 1 to 3). This
hole extended three vein set shapes by 95 m to 105 m down dip at Apollo Deeps and was drilled ~100 m
below and parallel to SDDSC108A (February 28, 2024). The hole included three intervals of > 20 g/t Au
(up to 54.4 g/t Au) and two intervals > 5% Sb (up to 23.4% Sb).
SDDSC123 was abandoned at 127 m due to the hole deviating from its original plan and was successfully
redrilled as SDDSC124.

and intercepted eleven mineralised vein sets (the ladder “rungs”) across Apollo East and Apollo Deeps. Two
high-grade vein sets were extended 20 m and 60 m down dip. SDDSC128 included 11 intercepts of Au >
20 g/t (up to 167 g/t Au) and 11 intercepts of Sb > 5% (up to 16.4% Sb). SDDSC145, currently
underway, has been designed to follow up high-grade results from SDDSC128 and SDDSC124.

being processed and analysed, with five holes (SDDSC092W3, 141, 142, 144, 145) in progress (Figure 1 and
2).
Further Information
Further discussion and analysis of the Sunday Creek project by Southern Cross Gold is available on the SXG
website at www.southerncrossgold.com.au.
No upper gold grade cut is applied in the averaging and intervals are reported as drill thickness. During future
Mineral Resource studies, the requirement for assay top cutting will be assessed.
Figures 1 to 5 show project location, plan and longitudinal views of drill results reported here and Tables 2
to 4 provide collar and assay data. The true thickness of the mineralize d intervals reported individually as
estimated true widths (“ETW”), otherwise they are interpreted to be approximately 40% to 70% of the
sampled thickness for other reported holes. Lower grades were cut at 1.0 g/t AuEq lower cutoff over a
maximum width of 2 m with higher grades cut at 5.0 g/t AuEq lower cutoff over a maximum of 1 m width
unless specified.
Critical Metal Epizonal Gold-Antimony Deposits
Sunday Creek is an epizonal gold-antimony deposit formed in the late Devonian (like Fosterville, Costerfield
and Redcastle), 60 million years later than mesozonal gold systems formed in Victoria (for example Ballarat
and Bendigo). Epizonal deposits are a f orm of orogenic gold deposit classified according to their depth of
formation: epizonal (<6 km), mesozonal (6-12 km) and hypozonal (>12 km).
Epizonal deposits in Victoria often have associated high levels of the critical metal, antimony, and Sunday
Creek is no exception. China claims a 56 per cent share of global mined supplies of antimony, according to
a 2023 European Union study. Antimony fea tures highly on the critical minerals lists of many countries
including Australia, the United States of America, Canada, Japan and the European Union. Australia ranks
seventh for antimony production despite all production coming from a single mine at Costerfield in Victoria,
located nearby to all SXG projects. Antimony alloys with lead and tin which results in improved properties for
solders, munitions, bearings and batteries. Antimony is a prominent additive for halogen -containing flame
retardants. Adequate supplies of antimony are critical to the world's energy transition, and to the high -tech
industry, especially the semi -conductor and defence sectors where it is a critical additive to primers in
munitions.
In August 2024, the Chinese government announced it will place export limits on antimony and antimony
products. This will put pressure on Western defence supply chains and negatively affect the supply of the
metal and push up pricing given China’s dominance of the supply of the metal in the global markets. This is
positive for SXG as we are likely to have one of the very few large and high-quality projects of antimony in
the western world that can feed western demand into the future.
Antimony represents approximately 20% in situ recoverable value of Sunday Creek at an AuEq of 1.88.
Technical Background and Qualified Person
The Qualified Person, Michael Hudson, Executive Chairman and a director of Mawson Gold, and a Fellow of
the Australasian Institute of Mining and Metallurgy, has reviewed, verified and approved the technical
contents of this release.
Analytical samples are transported to the Bendigo facility of On Site Laboratory Services (“On Site”) which
operates under both an ISO 9001 and NATA quality systems. Samples were prepared and analyzed for gold
using the fire assay technique (PE01S method; 25 gram charge), followed by measuring the gold in solution
with flame AAS equipment. Samples for multi-element analysis (BM011 and over-range methods as required)
use aqua regia digestion and ICP -MS analysis. The QA/QC program of Southern Cross Gold consists of the
systematic insertion of certified standards of known gold content, blanks within interpreted mineralized rock
and quarter core duplicates. In addition, On Site inserts blanks and standards into the analytical process.
MAW considers that both gold and antimony that are included in the gold equivalent calculation (“AuEq")
have reasonable potential to be recovered at Sunday Creek, given current geochemical understanding,
historic production statistics and geologically analogo us mining operations. Historically, ore from Sunday
Creek was treated onsite or shipped to the Costerfield mine, located 54 km to the northwest of the project,
for processing during WW1. The Costerfield mine corridor, now owned by Mandalay Resources Ltd contains
two million ounces of equivalent gold (Mandalay Q3 2021 Results), and in 2020 was the sixth highest-grade
global underground mine and a top 5 global producer of antimony.
MAW considers that it is appropriate to adopt the same gold equivalent variables as Mandalay Resources Ltd
in its Mandalay Technical Report, 2024 dated March 28, 2024. The gold equivalence formula used by
Mandalay Resources was calculated using Costerfield’s 2023 production costs, using a gold price of US$1,900
per ounce, an antimony price of US$12,000 per tonne and 2023 total year metal recoveries of 94% for gold
and 89% for antimony, and is as follows:
𝐴𝐴𝐴𝐴𝐴𝐴𝐴𝐴 = 𝐴𝐴𝐴𝐴 (𝑔𝑔/𝑡𝑡) + 1.88 × 𝑆𝑆𝑆𝑆 (%).
Based on the latest Costerfield calculation and given the similar geological styles and historic toll treatment
of Sunday Creek mineralization at Costerfield, SXG considers that a 𝐴𝐴𝐴𝐴𝐴𝐴𝐴𝐴 = 𝐴𝐴𝐴𝐴 (𝑔𝑔/𝑡𝑡) + 1.88 × 𝑆𝑆𝑆𝑆 (%) is
appropriate to use for the initial exploration targeting of gold-antimony mineralization at Sunday Creek.
